Karaka the Legend of Juno [EPUB ebook] 

In the distant future, all of mankind will face the greatest threat it has ever known. The balance between good and evil will be tested, and the fate of the galaxy rests with a small group of displaced time travelers who are racing to figure out who they are and what they are supposed to do. Juno is a system on the verge of war with Nerin, a race of ultimate evil beings. They believe to end their suffering is the genocide of all mankind. The crew of the Star Dancer, having dealt with the Nerin in the past, becomes entangled with Juno and her people. It is now a race to save Juno and restore order before the Nerin attack and destroy the system.
